Gum Rubber Sheets, knowns as Natural Rubber Gasket & NR Rubber Seal & O Ring. Gum Rubber & Natural Rubber, is mainly composed of hydrocarbon (polyisoprene), and it also contain a small amount of protein, moisture, resin acid,and inorganic salt, etc, which is derived from latex liquid extracted from rubber trees.
Natural Rubber & Gum Rubber Properties
Gum Rubber Sealing Gasket & Sheets has high elasticity, tensile modulus and tear resistance. And it also withstands good electrical insulation, abrasion resistance, and drought resistance. Besides, natural rubber &NR rubber materials has excellent processing, which make it easy to bond to other materials. Gum Rubber & Natural Rubber Sheets is superior to most synthetic rubbers gasket in comprehensive performance.
Gum Rubber & NR Rubber has good integrated performance than other materials, while it doesn’t work well in oxygen and ozone resistance, so Gum Rubber is easy to get changed. Gum Rubber Seal & Sheet also doesn’t work well in oil and solvent resistance & heat resistance.
